This invention relates to a force feed lubricator and distributor for locomotives and stationary engines.

The chief object of .the invention is to pro- 5 vide a positive supply of lubricant to an en gine of the stationary or locomotive type only when the moving parts thereof are movin under the influence of fluid pressure that b is doing work. v

The chief feature of the invention consists in the operation of a forced feed lubricator by the constantly applied pressure employed in the prime mover and associating therewith a distributorof a novel character also operable by fluid pressurel employed in the prime mover. In the'latter instance the distributor isfoperable by the differential diaphragm pressures, the larger diaphragm being associated with the lower pressure 2 which is intermittently applied. 1 f

i The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings Fig. 1 is a front view of a locomotive showing the invention associated therewith, the several parts of the piping being'shown diagrammatically. .2 is a side elevational view of the same. Flg.

3 is an enlarged central sectional view f the lubricator and the power connection therefor. Fig. 4 1s a sectional view taken on line 4-4 of Fig. 3 of the lubricator and in the direction of the arrows. Fig. 5 is a sectional view taken on line 5-6 of Fig. 3 and in the direction of the arrows and of the same mechanism shown in Fig.4, to wit,the power connection and the power unit. Fig. 6 is a central sectional view through the distributor.

In the drawings 11 indicates a locomotive having a boiler 12, cylinders 13 and 13 and supply-lines 14 and 14*. Associated with each supply line is a distributor herein indicated respectively by the numerals 15 and 15 4 Each distributor is connected by a conduit 16 to the source of high pressure steam, to wit, the conduit 14. A conduit '17 is connected to t-he distributor at one end and to the p engine cylinder supply at the other, thus subjecting the distributor to intermittent pres.- sure. A conduit 18 is connected to the lubricator indicated generally by the numeral 19. Said conduit 18 constitutes a high prespl-y oil ifi'om the ubricator to the distributor sure lubricant su ply line and serves to sup 15. v A line 20 connects the distributor to the supply line connected to, the cylinder and thus the lines 16 and 20 are connected through the distributor and form a by-pass leadingfrom and thence to the supply line 14 of the engine.

Reference will now be had to Fig. 6, wherein the details of the distributor devic e are shown. The body portion jindicat-ed NICE ,1

generally by the numeral 15 includesa pair of transverse communicating channels 21 and 22, The channel 21 communicates at one end with conduit 16 and at the other end with the conduit 20. A bushing 23has a tapered outlet .orpassage 24 discharging into said passage 21. The channel 22 recelves a sleeve 25 which terminates at the end opposite from the end communicating with the conduit 21 in a valve seat 26. A

valve27 is associated therewith and carries,

a stem 28 for aligning the coil spring 29 and abutting an'adjustable stop 30. The

valve27 also is extended and carries a body l portion 31 that hasa predetermined fit within said sleeve 25. A channel 32 communicates" with conduit'18 at one end and thus the lubri cator and is supplied with lubricant under 1 high pressure. The cap 33 carried by thedistributor 15 includes a valvechamber 34 and this valve chamber communicates with the conduit 21 when the valve 27 is removed from its seat 26 through the predetermined fit between the stem 31 and the sleeve i the engine. cylinder, and preferably the front end, and this occurs intermittently,

pressure is applied to chamber 39. Diahragm 38 moves toward the left with abutment 41.. This engages diaphragm 36 and moves thesame to engage the end of the stem 31 and unseat the valve 27 from its seat '26. 1 This permits the lubricant supplied by line '18 under. high pressure, to pass from the valve chamber 34 to the passage 21.

High pressure steam also is passed 1 thesame time t'hefspring 29 hasfseated the H valve. .27: andithe lubricant supply is Ydiscon valve, the latter being adjusted through abutment .30..v :-Wl1en the steam pressure suppliedto the chamber 39 isreleased by being exhausted to the atmosphere or passed nto a low pressure-cylinder or to, accessories'as is the commoapractice, the diaphragm 36;" becomes effective and returns diaphragm-3S to its original, position.
